0 70 10 11 v 1 15 J an 2 00 7 Infrared-suppressed gluon propagator in 4 d Yang-Mills theory in a Landau-like gauge


The infrared behavior of the gluon propagator is directly related to confinement in QCD. Indeed, the Gribov-Zwanziger scenario of confinement predicts an infrared vanishing (transverse) gluon propagator in Landau-like gauges, implying violation of reflection positivity and gluon confinement. Finite-volume effects make it very difficult to observe (in the… (More)
